Case report: The first case of Achromobacter xylosoxidans-related tunnel infection in a patient receiving peritoneal dialysis

RATIONALE Achromobacter xylosoxidans infection is mostly reported in immunocompromised patients. Until now, it is still rarely reported in patients undergoing peritoneal dialysis. PATIENT CONCERNS This is the 1st case of A xylosoxidans infection due to tunnel infection of a Tenckhoff catheter. DIAGNOSIS The diagnosis was confirmed by the report of culture. INTERVENTIONS Risk factors for this infection in peritoneal dialysis include uremia with an immunocompromised state, contamination due to inexperienced skills, and aqueous environment of the dialysate. OUTCOME We believe that finding the source of A xylosoxidans contamination is the most important aspect of the overall treatment of the infection. LESSONS Environmental investigation of suspected source contamination is warranted in those with A xylosoxidans infection. Once the diagnosis is made, removal of the Tenckhoff catheter should not be delayed.
